Piezoelectric sheet sensorsDue to their small size, thinness, and flexibility, piezoelectric sheet sensors are anticipated to find uses such as in vibration measurement of piping, engines, and curved surfaces on machines. Research is also underway on their use in low-frequency, high sound pressure environments, such in as wind noise measurement in cars.The Little Known Behind-the-Scenes of the R&D of Piezoelectric Sheet SensorsPorous piezoelectric sheets generate an electric charge when subjected to changes in sound pressure or vibration, and owing to their thinness, lightness, and flexibility, qualities not exhibited by conventional piezoelectric elements, they are likely to find a wide range of applications.We interviewed an engineer who has played a central role in developing sensors utilizing this material about the potential applications of piezoelectric sheet sensors and heard some behind-the-scenes stories of their development.Norio OkuboS&V Sensor Development Group, R&D Department, Technical Development Center. Joined Rion in 2012. He started working on research and development of electrets and impedance transducers as components of hearing aid microphones. He has since been placed in charge of the evaluation of all transducers handled by the group. In recent years, he has also been in-volved in feasibility studies on the application of sen-sors that use novel organic piezoelectric materials.IN THE BACKYARD10Introduction of an ultra-thin sensor that stands apart from its predecessorsThe porous piezoelectric sheet, a piezoelectric element capable of convert-ing low to high frequency vibrations into electrical signals, is the fruit of joint research between Rion and the Kobayasi Institute of Physical Research. In addi-tion to being able to measure sound pres-sure and vibration when used as a sensor, these paper-thin light weight sheets enable installation in tight spaces, with little impact on the object being mea-sured.Norio Okubo of the S&V Sensor Development Group, who was instru-mental in the development of this inno-vative sensor using porous piezoelectric sheets, says the following about them.“Simply put, a porous piezoelectric On the Front Lines of Technology Development Endless Possibilities for ApplicationWhat Are the Possibilities of Piezoelectric Sheet Sensors Made Using Porous Piezoelectric Sheets?
